4. KEEP RIDERS OFF EXCAVATORKEEP RIDERS OFF EXCAVATOR
Only allow the operator on the excavator. Keep
riders off.
Riders on excavator are subject to injury such
as being struck by foreign objects and being
thrown off the excavator. Riders also obstruct
the operator's view resulting in the excavator
being operated in an unsafe manner.
MOVE AND OPERATE MACHINE SAFELYMOVE AND OPERATE MACHINE SAFELY
Bystanders can be run over. Know the location
of bystanders before moving, swinging, or
operating the machine.
Always keep the travel alarm in working
condition. It warns people when the excavator
starts to move.
Use a signal person when moving, swinging, or
operating the machine in congested areas.
Coordinate hand signals before starting the
excavator.
OPERATE ONLY FORM OPERATOR'S SEATOPERATE ONLY FORM OPERATOR'S SEAT
Avoid possible injury machine damage. Do not
start engine by shorting across starter
terminals.
NEVER start engine while standing on ground.
Start engine only from operator's seat.
PARK MACHINE SAFELYPARK MACHINE SAFELY
Before working on the machine:
·Park machine on a level surface.
·Lower bucket to the ground.
·Turn auto idle switch off.
·Run engine at 1/2 speed without load for 2 minutes.

5. SUPPORT MACHINE PROPERLYSUPPORT MACHINE PROPERLY
Always lower the attachment or implement to
the ground before you work on the machine. If
you must work on a lifted machine or
attachment, securely support the machine or
attachment.
Do not support the machine on cinder blocks,
hollow tiles, or props that may crumble under
continuous load.
Do not work under a machine that is supported
solely by a jack. Follow recommended
procedures in this manual.
SERVICE COOLING SYSTEM SAFELYSERVICE COOLING SYSTEM SAFELY
Explosive release of fluids from pressurized
cooling system can cause serious burns.
Shut off engine. Only remove filler cap when
cool enough to touch with bare hands.
HANDLE FLUIDS SAFELY-AVOID FIRESHANDLE FLUIDS SAFELY-AVOID FIRES
Handle fuel with care; It is highly flammable.
Do not refuel the machine while smoking or
when near open flame or sparks. Always stop
engine before refueling machine.
Fill fuel tank outdoors.
Store flammable fluids away from fire hazards.
Do not incinerate or puncture pressurized
containers.
Make sure machine is clean of trash,
grease, and debris.
Do not store oily rags; They can ignite and
burn spontaneously.

6. BEWARE OF EXHAUST FUMESBEWARE OF EXHAUST FUMES
Prevent asphyxiation. Engine exhaust fumes
can cause sickness or death.
If you must operate in a building, be positive
there is adequate ventilation. Either use an
exhaust pipe extension to remove the exhaust
fumes or open doors and windows to bring
enough outside air into the area.
REMOVE PAINT BEFORE WELDING ORREMOVE PAINT BEFORE WELDING OR
HEATINGHEATING
Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when paint
is heated by welding, soldering, or using a torch.
Do all work outside or in a well ventilated area.
Dispose of paint and solvent properly.
Remove paint before welding or heating:
· If you sand or grind paint, avoid breathing the
dust.
Wear an approved respirator.
·If you use solvent or paint stripper, remove
stripper with soap and water before welding.
Remove solvent or paint stripper containers
and other flammable material from area.
Allow fumes to disperse at least 15 minutes
before welding or heating.
ILLUMINATE WORK AREA SAFELYILLUMINATE WORK AREA SAFELY
Illuminate your work area adequately but safely.
Use a portable safety light for working inside or
under the machine. Make sure the bulb is
enclosed by a wire cage. The hot filament of
an accidentally broken bulb can ignite spilled
fuel or oil.

7. SERVICE MACHINE SAFELYSERVICE MACHINE SAFELY
Tie long hair behind your head. Do not wear a
necktie, scarf, loose clothing or necklace when
you work near machine tools or moving parts.
If these items were to get caught, severe injury
could result.
Remove rings and other jewelry to prevent
electrical shorts and entanglement in moving
parts.
STAY CLEAR OF MOVING PARTSSTAY CLEAR OF MOVING PARTS
Entanglements in moving parts can cause
serious injury.
To prevent accidents, use care when working
around rotating parts.
AVOID HIGH PRESSURE FLUIDSAVOID HIGH PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the
skin causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten
all connections before applying pressure.
Search for leaks with a piece of cardboard.
Protect hands and body from high pressure
fluids.
If an accident occurs, see a doctor immediately.
Any fluid injected into the skin must be
surgically removed within a few hours or
gangrene may result.

8. AVOID HEATING NEAR PRESSURIZEDAVOID HEATING NEAR PRESSURIZED
FLUID LINESFLUID LINES
Flammable spray can be generated by heating
near pressurized fluid lines, resulting in severe
burns to yourself and bystanders. Do not heat
by welding, soldering, or using a torch near
pressurized fluid lines or other flammable
materials.
Pressurized lines can be accidentally cut when
heat goes beyond the immediate flame area.
Install fire resisting guards to protect hoses or
other materials.
PREVENT BATTERY EXPLOSIONSPREVENT BATTERY EXPLOSIONS
Keep sparks, lighted matches, and flame away
from the top of battery. Battery gas can
explode.
Never check battery charge by placing a metal
object across the posts. Use a volt-meter or
hydrometer.
Do not charge a frozen battery; It may explode.
Warm battery to 16。C (60。F).

PREVENT ACID BURNSPREVENT ACID BURNS
Sulfuric acid in battery electrolyte is poisonous.
It is strong enough to burn skin, eat holes in
clothing, and cause blindness if splashed into
eyes.
Avoid the hazard by:
1. Filling batteries in a well-ventilated area.
2.Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte
is added.
4. Avoiding spilling of dripping electrolyte.
5. Use proper jump start procedure.
If you spill acid on yourself:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize
the acid.
3. Flush your eyes with water for 10-15
minutes. Get medical attention immediate-
ly.
If acid is swallowed:
1. Drink large amounts of water or milk.
2. Then drink milk of magnesia, beaten eggs,
or vegetable oil.
3. Get medical attention immediately.

USE TOOLS PROPERLYUSE TOOLS PROPERLY
Use tools appropriate to the work. Makeshift
tools, parts, and procedures can create safety
hazards.
Use power tools only to loosen threaded tools
and fasteners.
For loosening and tightening hardware, use the
correct size tools. DO NOT use U.S.
measurement tools on metric fasteners. Avoid
bodily injury caused by slipping wrenches.
Use only recommended replacement parts.

Improperly disposing of fluids can harm the
environment and ecology. Before draining any
fluids, find out the proper way to dispose of
waste from your local environmental agency.
Use proper containers when draining fluids. Do
not use food or beverage containers that may
mislead someone into drinking from them.
DO NOT pour oil into the ground, down a drain,
or into a stream, pond, or lake. Observe
relevant environmental protection regulations
when disposing of oil, fuel, coolant, brake fluid,
filters, batteries, and other harmful waste.
